GEORGE H. MILLER, 01 BROOKLYN, NEW YORK.

Specification of Letters Patent. Application filed Jul 11,1913. Serial No. 778,500.

Patented Aug. 4., 1914 To all whom it may concern:

Be it I: own that l, Gnonon H. Mnmnn, a citizen (ii the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented certain in Printing- Presses, of which the following is a specification. I

This invention relates to printing presses and more especially to presses adapted to print two or more colors, and consists of simple means capable of being attached to press at a very moderate cost, which with the proper arrangements of the forms, will reduce the presswork to one-half the impressions usually re-' uired, as will be more fully described in tie following specification, set forth in the claim and illustrated in the accompanying drawings, wherein:

' Figure 1 is a plan view of the bed and nk plate of a cylinder press. Fig. 2 is a side view of the same. I Fo 3 is an enlarged plan view of the ink plate. Fig. 4 is a longitudinal sectional view ofihe same. Fig. 5 is a front end view of the plate. Fig. 6 is a perspective view of the filling strip.

The two-color printing press now commonly used requires nearly double the amount of mechanism required for a single color press and the impressions are made at dil'l'erent times. Nevertheless two impres sions are necessary, one for each color at ditl'm'cnt times as the paper passes through the press.

The present invention provides for a simple adaptation of the one color press so that it can he used for two colors and at the same time but half the usual number of impressions are necessary. In order to accomplish this end the 'lormsfor the two colors are operated side by side instead of following each other, and the fountain is divided b a partition so as to contain two ditl'erent inks and the ink plate also divided to separate these inks.

The drawings show the end portion of a cylinder printing: press with the ordinary reciprocating bed 10 carrying the chase ll with its "form, and extending beyond the bed is the ink plate 12 which may be secured to the longitudinally moving rails 133 by screws for removal if desired, The ink a central point with a longitudinal groove I l and into same is littcd a strip 15 flush with the surface of the plate and having on its lower side studs 1G to fitinto )erforations in the groove and prevent the ongitudinal movement of the plate. The studs 16 are inclined and the front end of the plate carries a. gravity latch 17 to hold the strip against movement in that direction. i

The ink fountain 18 may be -of the usual type and provided with one or more blocks 19 to completely fit between the walls of the fountain so that diflerent colored inks may be contained in the compartments formed by the block. The usual distributing rollers 20 are employed but the composition is cut away midway of their length or at a point corresponding with the block 18. This removed part of the rollers also corresponds with the groove 14, of the ink plate so that when two colors of ink are used, thev are effectually separated on the plate and are thoroughly intact. The ink being taken up by rollers 21 they are also p 'actically divided and other rollers may be used and set slightly at an angle to more thoroughly distribute the ink which is to be applied to the forms in the chase 11.

In adapting; this device for printing in two colors the two forms 22 and 23 are placed side by side but their tops are reversed. Ditl'erent colored inks are placed in the compartments of the fountain 17 and distributed on the two sides of the ink plate and finally to the two forms. In case red ink is used on the form 22 and'black on form .23 they are prevented from mixing and blending by the groove 14 and half of the desired number of sheets are printed at the same time from the two forms. If a job of a thousand sheets is desired, five hundredimpressions are made with one end of the sheet .from the red form and the other end from the black form. The five hundred sheets are again run through the press after being turned so that the black impressions will receive the imprint of the red side and vice versa, the two colors being interlincd or mingled as-desired but one thousand two-color sheets are thus obtained with but one thousand impressions where two thousand impressions have heretofore been required.

The mechanism asabove described may be used for printing small forms in one color or it may be used for several small forms at one time in a single color as for two colors, but when it becomes necessary to use single color by simply filling the groove 14 with thelstrip 15 and locking; the same therein by 'means of the latch 17. The strip beingfiush with the balance of the plate the latter becomes to all intent and purpose a single ink plate of large surface.

- It is obvious that the device may be so modifiedas to'apply .it to presses where more forms than two are used, or the details may be altered or changed without departing? from the essential features above described or the scope of the appended claim.

In actual use it may not be found neces' sary to ,cut' away the composition rollers 20 and 21 but the grooved vibrating rollers 20' and 21 in connection with the block 19 and groove 14, inay be sufficient to separate the hike without inutilating th v regular mking and distributing rollers.

tion of the block, an ink plate with a groove and inclined perforations, a strip with studs for the perforations and a gravity latch to hold the strip in the groove.

Signed at New York in the county of New York and State of New York this 30th day of June A. D. 12113.
